indirect bilirubin cannot be measured in the urine.

Indirect bilirubin is in the form of unconjugated bilirubin which is insoluble to water and it is non polar in nature, another is that bilirubin is binded to albumin, which result to high molecular weight that's the reason why it cannot pass to the glomeruli for the glomeruli can only pass through molecules having lower molecular weights.

Low / No Urobilinogen and High Bilirubin in urine with high levels of bilirubin in the blood means Obstruction of Bile ducts/Obstructive jaundice Urine positive for Ketones means diabetic ketoacidosis, the patient is diabetic or having a crash diet. High glucose level in urine means lack of control of the diabetes High glucose level and normal blood sugar level means lowered renal threshold. Marked High Protein level in the urine means Nephrotic syndrome, Renal vein thrombosis, Amyloid disease, Lupus erythematosus. (4 gms/day) High protein level and heated at 100 C becomes normal/low protein level means multiple myeloma/macroglobulinemia. There are more informations if you bought the urinalysis book.
